OIL EXTRACTION EQUIPMENT

The first and foremost step for oil extraction is the cleaning of seeds and their processing. This is done so that the oil seeds are cleaned and separated from the many unwanted particles such as dust, hulls, husks, metals, glass, etc. This results in a better and purer yield of oil. In order to extract the oil from these seeds, a process called oil extraction is followed. The oil seeds are crushed by using an equipment that is known as Oil Expeller or Oil Press.

During the earlier times, the extraction of oil was done by crushing the oil seeds with the use of stone grinders and other mills. Now oil expelling / extraction is done by making use of oil expelling equipment or machines. The machine that is used to extract oil is known as an Oil Expeller / Screw Press. These are further categorized into Pre Press Expeller, Full Press Expeller, and Cold Screw Press. Today, manufacturers from all over the world are coming up with innovative and technologically advanced Oil Expelling Equipment for small capacity as well as large capacity oil plants.

Oil expelling is a mechanical method that is used to extract oil from oil seeds like Sunflower seeds, Safflower seeds, Groundnuts, Soybeans, Rape seeds, Mustard seeds, Castor seeds, Copra, Cotton seeds, and many more. All oil seeds contain some amount of oil in them. It varies from 20% to 60%. In order to extract the oil content from them, the oil seeds have to be crushed or squeezed under a high pressure in one step. As the seeds are pressed, it produces a friction which causes the seeds to heat up. As the heat of the expellers increase, the yield of the extracted oil also increases.

The biggest advantage of using Oil Expellers is that the oil that is extracted through the use of such machines is organic and 100% free of all chemicals. The use of chemicals increases the oil yield by a large quantity, but they are not very pure and healthy. Whereas, the oil extracted by using Screw Presses do not need the use of any kind of chemical. Even though the yield is lesser, it is much healthier and purer.

Today, oil mill machinery manufacturers are coming up with a wide assortment of expelling equipment for oil extraction. The modern Expelling machines are assembled with accuracy and precision, so that each process that goes into the expelling of the oil seeds is carried out in an efficient manner. This leads to maximum oil yield. These equipment are available everywhere at minimum cost.
